The Feast of Saints Peter and Paul or Solemnity of Saints Peter and Paul is a liturgical feast in honour of the martyrdom in Rome of the apostles Saint Peter and Saint Paul, which is observed on 29 June. The celebration is of ancient origin, the date selected being the anniversary either of their death or of the translation of their relics.
Saint Peter (died c. 64 AD), also known as Simon Peter, Simeon, or Simon, according to the New Testament, was one of the Twelve Apostles of Jesus Christ, leaders of the early Christian Church. The Roman Catholic Church considers him to be the first Pope, ordained by Jesus in the “Rock of My Church” dialogue in Matthew 16:18. The ancient Christian churches all venerate Peter as a major saint and associate him with founding the Church of Antioch and later the Church in Rome, but differ about the authority of his various successors in present-day Christianity.
Paul the Apostle, originally known as Saul of Tarsus was an apostle (though not one of the Twelve Apostles) who taught the gospel of Christ to the first-century world. He is generally considered one of the most important figures of the Apostolic Age. In the mid-30s to mid-50s, he founded several churches in Asia Minor and Europe. Paul used his status as both a Jew and a Roman citizen to advantage in his ministry to both Jewish and Roman audiences.
